HiIam from a Gear Manufacturing Industry. I need help in following items

1) In our company, the lot size of orders are very small in many cases like from 1 to 5. Operator spends more time in setting that the process time.Can someone share their knowledge on what kind of work holding/fixtures are typically used to reduce setting time especially in machining operations like "Turning, Hobbing, Drilling/Tapping, Grinding.

2) Can some one throw lights on hybrid/Mixed machine layout design for a gear industry?Appreciate you sharing the information.
